HARNESS-TERRET.

SPECIFICATION forming part of Letters Patent No. 373,631, dated November 22, 1887.

Application filed April 4, 1887. Serial No. 233,558. (No model.)

To all whom it may concern.-

Be it known that I, JOHN ALEXANDER, of Hartford, in the county of Hartford and State of Connecticut, have invented a new Improvement in Harness-Terrets; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a face view of a terret complete; Fig. 2', a perspective view of the hard-metal body; Fig. 3, a vertical central section through the terret complete in the plane of the ring; Fig. 4, a transverse vertical section of the complete terret; Fig. 5, the same invention as applied to a water-hook.

This invention relates to an improvement in the construction of the parts of harness-trimmings which are fixed to the saddle as guides for the driving-reins, and also for the waterhook. These articles must necessarily possess considerable strength, as great strain is brought upon them in the use of or in handling the harness, and they have generally been made of cast metal possessingsuflicient strength for the purpose; but such construction is expensive,both as to material as well as finishing.

The object of my invention is to produce these articles so that they necessarily possess even greater strength than the cast-metal articles referred to, but yet are produced at a comparatively trifling expense; and the invention consists in forming a body of hard metalas iron or steel-of a shape corresponding to the terret or water-hook to be produced, but of less extent in transverse section, and then casting a soft cheaper metal upon this hardmetal body to give the required surface shape to the terret or water-hook, as more fully hereinafter described.

In illustrating my invention I will first do so as applied to a terret and then describe the water-hook as a modification thereof.

In the construction of a terret such as represented in Fig. 1, I first form a hard-metal body-as iron or steel by taking a strip of such hard metal of less area in transverse section than the corresponding transverse sec-- tion of the complete terret. This strip I bend into shape, as seen in Fig. 2, forming a ring, A, and a radial projection, B, therefrom, which is to form the body for the shank of the terret. A mold is made for the complete terret, as in the usual manner for casting such terrets.

The body, Fig. 2, is introduced into the mold in like manner as a core would be introduced were the terret to be cast hollow. Then the metal, preferring that commonly known as white metal, is poured into the mold around the body, so as to completely inclose it, as seen in Figs. 3 and 4, and present a complete surface of the cast metal. The metal surrounding the projection 8 forms the shank or bolt C, by which the terret is secured, and at the junction of the shank and ring a suitable base, D, is formed, so that when the terret is complete it is of substantially the usual form, but has inclosed within it a hard strong metal, giving to it much greater strength than can be produced by any suitable cast metal. The surface of the terret is then finished by electroplating, japanning', or any known methods of finishing, and the terret, while very cheap in construction, possesses equal strength and nicety of finish with the most expensive terrets.

A water-hook is represented in Fig. 5 in vertical central section, which differs only fromthe terret in the fact that it is open upon one side for the introduction of the checkrein. By the term terret, therefore, I wish to be understood as including not only the guiderings or terrets proper, but the water-hook.

I have described the invention as employing a cheap metal, and such is the general design of my invention; but it will be understood that if it be desired to employ an expensive metal, such metal may be cast around the iron body and present a solid expensive metal surface. In that case not only is the terret strengthened, but the cost of the terret is reduced by so much as the difference in the cost between the two metals.

I am aware that it is not new to cast a soft I I claim covering of other metal cast upon said body 10- As an improved article of manufacture, the and said shank portion, and so as to give the herein-desoribed harness-terret, consisting in finished shape to the said terret and form th a hard-metal body, the said body bent into shank, substantially as described. 5 the general form of the terret, and with one end turned radially therefrom corresponding JOHN ALEXANDER" to the shank of the terret, said body and shank Witnesses: being of less transverse area than the corre- J OHN E.
